Strange font definition

Hello Donald and all other readers,

Thanks for your plugin! It is great.
And… I wish you (all) happy 2016… and all years to come.

I am using Spacious on a test site with your plugin.

When the pages are listed the font is not as I would like it to be (as it is all over the site) but different.

With FireBug I have checked it, and it is defined as
\"Lato\",​​sans-serif
with these two back slashes.

How can the style be put back to “normal”, unchanged?

The pages are:
http://wata-test3.int.world/poetry-wata
code: [subpages]

http://wata-test3.int.world/gallery/
code: [subpages]

and here only the details, the text under the names:
http://wata-test3.int.world/teachers/
code: [pagelist_ext show_image="1" sort_column="post_title" class="listclass"]

Thanks,

Tamás
